Question

3C + 2D = 1

-2D + 3C = 0

The solution to this system of two equations is:

C = 3/13
D = 2/13

Can someone please show all the working to prove if this is correct. Thanks

Answer 1

The solutions are wrong.

Answer 2

What do you get?

Answer 3

3C = -2D +1 => C = (-2D+1)/3
-2D + 1 -2D = 0 => -4d = -1 => 4d = 1 => d = 1/4

Answer 4

Now you have D, just stick it in the first equation to get C.
